Andy and diane want to buy a new van. they are allowed $5,500 for their present car. they also made a down payment of $2,300. they still owe 40% of the regular price of the car. what is the regular price of the car

The regular price of the car is $13,000.

Step-by-step explanation:

i) let the price of the van Andy and Diane want to buy be $x.

ii) they get $5,500 for their present car

iii) they also make a down payment of $2,300.

iv) therefore $x = $0.4x + $5,500 +  $2,300

   therefore $0.6x = $7,800

therefore $x = $ = $13,000

The regular price of the car is $13,000.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
